DENVER -- NFV & Carrier SDN -- The ability to deliver new services faster remains the top driver for network functions virtualization, according to new Heavy Reading research presented here today. Cutting costs -- both opex and capex -- comes in a hard second, followed by increased revenue generation. And there is particular interest in key high-value use cases such as virtual CPE, software-defined wide area network and security services.
At a midday presentation here today, Heavy Reading Senior Analyst Jim Hodges laid out research, sponsored by Juniper Networks Inc. (NYSE: JNPR), which showed network operators realize the need for interrelated capabilities to drive NFV forward, such as capex and opex reduction, but also high-value use cases.
"The survey research identifies that network operators have clearly defined preferences in terms of what constitutes a high-value use case," Hodges said. "They also have formed strong opinions on the benefits that implementing these use cases will have from both a technical and business perspective. The three uses we are addressing at today's lunch session -- vCPE, SD-WAN and Security -- are all in demand because they are well-suited to leveraging the automation, scale, and application acceleration characteristics of the cloud to meet current market needs."
What is emerging now is a holistic NFV implementation model that relies heavily on automation, application acceleration policy, third-party software integration, managed services and security capabilities, Hodges said.
When asked to rank VNFs by priority, service providers in the survey ranked security services first, followed by managed communications services, SD-WANs, customized managed services and virtual CPE.
The top drivers for SD-WAN deployment were opex reduction followed by capex reduction and guaranteed consistent and reliable performance for any application.
Firewall protection is the key application in today's virtual CPE, Hodges said, but that is shifting in the months ahead as "interest and intent to deploy other capabilities, such as content filtering and application security and detection, rapidly gain in popularity."
